I'm facing a problem that I am unable to solve for a while. I need to read a KMN5X000ZM-B209 EMMC from a Nokia Lumia Windows 8 phone, and so far I have been unable to do so. The EMMC contains vital data that I cannot afford to loose.

I have purchased both the Easy JTAG Box and the Advance Box. I have seen this exact EMMC type being mentioned in the 12.40 update for Advance Box, but I have been unable to read it yet. I received a wiring diagram for the EMMC in another topic, although I have not been able to verify it, and had a specialist do the soldering work to connect the EMMC. So far, without success. I am either getting 0x5E5E5E responses from the ATF Box, and a general error message from the Easy JTAG Box.

I have contacted the shop and the company of the Advance Box, but they haven't responded to my e-mails asking for any paid service anywhere in the world to make this work. So all I'm stuck with is a bunch of expensive hardware, no manual, no clear error message, and no support from both the shop and the creators.

If anyone has a fail-safe method to read the full EMMC, without any risk of damaging it, I am willing to pay good money. In fact, I am flat out offering $1000 right now to the person or company that can prove to me that they can safely do it, and of course after receiving the full EMMC dump.

I live in The Netherlands, but I am willing to travel anywhere, as long as success can be guaranteed. If the software settings are to be checked, I can do video chat (Skype or otherwise) and will also pay for your help if any significant progress is made. If I need different hardware, different software or different wiring of the EMMC that can also be arranged.

As you can read above, I am quite desperate for a solution at this point. If you can help me, or know someone who can, please respond to this post or in a PM.

Thank you!

You mention a lot about first guaranteeing success. This is not possible, and anyone guaranteeing success before an attempt is a fool. Confident of success, yes.. but not guarantee. we have no idea what was wrong with the phone, the eMMC could be shorted, dead, corrupted or otherwise faulty. It is not clear where the DATA you need is, if it is on the raw NAND, in another part of the eMMC, unencrypted, in a format that is recovereable etc.

I cant stress enough that you should only perform actions on a device that holds DATA you cannot afford to lose when you are pretty sure you know what the result of those actions would be.

The best course of action would be to get an identical device and do all your experimentation on that. Not cheap I know, but if the DATA is as important as you believe, this is the only way really. I think it is like doing a head swap on a HDD for the first time but on a disk holding your valuable DATA.

All that said, reading from the eMMC is likely going to be done by unsoldering it and reading it either in an eMMC reader or by accessing the RAW NAND (likely undocumented) pads.

I have some eMMC's here now to read, there are a few different types, the eMMC part being fairly standard but raw nand pads nowhere near it.

So I see you have tried the GSM forums and no luck there. did you by any chance take a picture of the pad side of the eMMC?

also, a picture of the PCB where the eMMC was would be good as well.

if you can deduce the SD pinouts from the eMMC spec, you might be able to read it using sd card slot. an SD-eMMC socket would be the best way though, then you should be able to image it with dd.

I am confident I could read the eMMC if there is nothing wrong with it.
